.1, This invention rent-es t6 glue-dispensing ap Paratus and particularly-'- to apparatus. for applying" glue in the operation" of sealing cartons or similar containers or a plying a relatively wide him of glue to the surface of an article to be glued.

An object of the invention is to produce a simple and easily operated glue-dispenser which is portable and" is equipped with means" for auto= matically closing the glue' delivery port or orifice forming a part thereof, when the device is not in use.

A further object is to' produce a glue-dispenserwhi'ch-isof simple construction and is so fabricated and arranged thatit may be operated and the supply of glue simultaneously controlled by the action" of one hand only of the operator;

A further object is to provide-- agluedispensing' device which is so' constructed and arrangedthata variation in the grip of the operator's hand on theoperatinghandle of the device; will open or close a glue delivery ori frce forming a part of the device.

A further object is to provide a glue-dispensing device which is provided: with a two-part handle so arranged that it may be simultaneously employed in moving the device during the 'I'n' the'draw-ings,- Figure l is a side view of a glue-distributing device embodying my invention; Figure 2 isan eiidview of the deviceshown in F-igure 1; Figure 3 isa top plan View of the device" shown in Figures land 2 and Figure 41 is a sectional View of a portion of the device taken along the line IVIV of Figure l.

Referring: to the drawings the apparatus consists essentiallyof' a glue container 5, a gluedistributing roller .6 and means, shown in the form of a two-part handle 1, adapted to be employed" in the operation of guiding the roller 4 Claims; (Cl. 91 -62.5)'

2. up of two parallel members 8 and two annular members 9 which are secured to the m'emb fs" 8' preferably by Welding. The roller 6 is provided with an axle H when is s itablysecured thereto and whichis adapted to' be held in place ohthe framemembcrs 8" by means of latches t2". 7

The glue" container 5' is movably mounteh orr the frame, and is surrounded and slideably" en gageu' by the annular frame members 9=. Aglue delivery orifice I3 is formedin the bottom of the container" 5, and whi'l'ethe" container is generaliy' cylindrical; the'lower portion-thereof is'so formed' thatthe orifice t3 extends diametrically, with relation to the cylindrical portion of the container, and is" substantially as long asthe diam-* eter' of such portion of the container. It also extends substantially throughout the length of the roller 8% The container is moved toward and away from The grip I 5 is lo'eated' between and isSecured:

to the upper ends of the frame members 8; whereas the grip l4- is s'ecu'red to ahandle-member- Hishown in the drawings as a metal part.-

in the form of a :U -shape'd part or stirrup Sf cur-ed: to the top of the container preferably;

by soldering or welding. As shown, th grip it,

is: located between the upper ends'oi the stirrup.

It; and is secured thereto by means of screws ll; The upper: ends of the frame members 3' are" spread? apart to* accommodate the inter-- positioning of thestirrup member it and the along a path on which a film of glue is to be placed and also to controlthe supply of glue issuing irom the container \ontothe roll-e171- As Shown, the device includes a frame portion made handle grip 1'4; The handle grip i5 is shown as secured to the frame members't by means of screws I8.

'Il e r ps it and-t5 arehclcic epelzat ve relation with each other by means of strip er crew 19- As'showinincfi ure e, ach s rew 9 xt nd hrone hua two-d ameter bore 21, formed will be apparent that the two screws I9 cooperate with the handle grip so as to hold the grip M in substantially parallel relationship with the grip l5 during relative motion between the grips.

As shown in Figure 4, the aperture in which each screw i9 is secured, is countersunk so as to provide a nest for a coiled spring 22. As shown, each spring 22 surrounds one of the screws I9, seats at one end on the bottom of the countersunk portion of the aperture and at the other end on the adjacent face of the grip 15. Thus the two springs 22 cooperate to yieldingly hold the grips l4 and I5 apart and to hold the container 5 in orifice-closing position with relation to the roller 6. With such an arrangement the device may be actuated by an operator who grips the two-part handle 7, and the operator may vary the amount of glue delivered from the container to the roller 6 by varying his grip on the two-part handle I, i. e., by manipulating the fingers of the hand holding the handle I.

As shown in Figures 1 and 3 the handle grip l5 carries a stop screw 23 which is located within an aperture extending through the grip l5 and is adapted to project beyond the inner face of that grip and thus form an adjustable stop for limiting the approach of the grip 14 toward the grip l5. It is, of course, apparent that the position of the screw with relation to the grip 14 may be adjusted by merely turning the screw, and in this way the extent of opening of the glue-delivery aperture [3 may be controlled. The container 5 is shown as provided with a filling aperture in the upper end thereof and the aperture is shown provided with -a closure in the form of a screw plug 24.

I have provided simple and effective means for removably securing the roller 6 in place on the frame members 8. As shown, each member 8 is formed with a short slot 25 which extends upwardly from the lower end thereof and is so arranged that the inner end thereof forms a bearing or a seat for the axle H. Each latch I2 is pivotally mounted on a frame member 8 and each is provided with an arc-shaped slot 26 in one lateral edge thereof which is so positioned with relation to the pivot point of the latch that the axle l I is engaged thereby when located against the end of the slot 25. As shown, each frame member 8 carries a bolt 21, which constitutes a pivot support for one of the latches l2 and which is fitted with a wing nut 28 for securing the latch in an adjusted position, such for example as the position illustrated in Figure 2. Thus the members 8 and the latches i2 cooperate through the agency of their respective slots 25 and 26 in holding the roller '6 in place on the frame of the dispensing device.

It will be apparent that the roller 6 may be rotatably mounted on the axle II in which case the slots 25 and 26 may be so formed as to lock the axle in position on the frame of the dispenser. On the other hand, the axle Il may be rigidly secured to the roller 6, in which event the slots 25 and the slotted end of the members 8 will be so formed as to constitute bearings in which the axle is rotatably mounted.

As previously stated the springs 22 cooperate in tending to move the container 5 against the roller 6 so that the orifice I3 is closed by the engagement of its edges with the peripheral surface of the roller 6. In order to employ the device as a glue-distributor, the two-part handle I is grasped by the operator and the device is moved to posi toward and away from said rollerand encircled tion so that the roller 6 is located in a selected position on the surface to which glue is to be delivered. The operator then manipulates the handle grip M by increasing the pressure of his fingers on that grip and in this way moves the container away from the roller 6. This has the double effect of releasing the roller so that it may rotate about its axis and of also opening the delivery port l3 a greater or less amount. The movement of the roller along the surface engaged by it contributes to a flow of glue onto the peripheral face of the roller, and also distributes a film of glue along the surface of the material engaged by the moving roller. Under normal operating conditions the stop screw 23 will be adjusted to control the extent of opening of the delivery orifice l3, consequently the operator may open the delivery orifice by merely gripping the two-part handle I. It will, however, be apparent that the operator may vary the degree of orifice opening by varying the pressure of his fingers on the grip l4.

From the foregoing, it will be apparent that the glue-distributing device is of simple construction and is one which may be readily assembled and disassembled. The roller 6 may be readily removed from the frame by merely manipulating the latche 12 to move them out of engagement with the axle H and then in moving the frame members 8 out of engagement with the axle. The container 5 may likewise be readily removed from the frame portion by simply removing the handle grip l5 from its position between the frame members 8 and then lifting the container out of engagement with the rings or annular members 5 forming a part of the frame portion.

While I have illustrated and described but one embodiment of my invention, it will be apparent that various changes in, additions to and omissions from the illustrated apparatus may be made without departing from the spirit and scope of my invention as defined by the appended claims.
